The results indicated that the pesticide could be distributed through the body and cumulated in peripheral compartment relatively,but it could be eliminated rapidly.With parameters such as t1/2α valued 3.40min,t1/2β 59.03min and Cl 0.018ml·min-1,Its metabolism followed two-compartment open model after administration of 10 mg/kg.It was primary distributed to blood-riched organs and fat tissues and ready to be biotransformed.The metabolic product were detected in choler,which had stronger polarity with retention time 4.25min;and no parent compound was found in both urine and faeces.Key words: Toxicokinetics;Fenamithion;Organophosphorus pesticide

结果显示：螨胺磷在体内全身分布，并有周室富集，消除较快，在10mg/kg静脉注射呈二室模型，t1/2α为3.40min，t1／2β为59.03min，全身清除率Cl0.018ml·min-1；螨胺磷主要分布于血流量大的器官及脂肪组织；螨胺磷在体内不稳定，能被肝脏代谢转化成极性更高的化合物后经由胆汁排出，该成分可在同样的色谱条件下被分离，峰保留时间4.25min；粪尿中均未检出原药。

The author investigated the community of grasshoppers in Changbai Mountain area during the period of July to September 2001, complementally collected specimen and systematically collected and measured environmental factors from July to October in the following year, and consulted to specimen collected by Fengling Zhang and Yanlong-yang in 1979, 1980 and 1981. By analyzing and classifying the data of five years, the author analyzed the community construction and ecological adaptability of the grasshoppers in the area. The main aspects dealing with the grasshoppers are as follows:(1)the community construction and faunal geographical elements;(2)characteristics of their ecological distribution;(3)vertical distribution of grasshoppers in the northern slop;(4)the relationship between environmental factors and differences in shape of grasshoppers in different vertical belt of northern slop, etc.

本文作者于2001年7～9月间系统地调查了长白山地区的蝗虫，并于2002年的7月到10月间对标本进行了补充采集，并对环境因子数据进行了系统的测量和收集，同时参考张凤岭、杨彦龙先生1979、1980和1981三年采集的标本，通过对标本的鉴定和整理，采用五年的野外工作数据，对长白山地区蝗虫群落结构及生态适应特性进行了研究，主要研究内容包括：蝗虫的群落结构及区系地理成分；蝗虫生态分布特点；保护区北坡蝗虫垂直分布及不同垂直带内蝗虫的形态差异和环境因子之间的关系等方面内容。
